[iOS] Player crashing when connecting external Display via USB-C port
Reproduction steps:
1. Open the project in "bug.zip"
2. Build for iOS
3. Connect an external display to the device using a USB-C port
4. Wait for the view to show up in the external monitor
5. Move around in the game using to fingers
Expected result: Nothing significant related to memory happens
Actual result: Memory will increase very fast and the application will crash
Reproducible with: 10.5.0 (2020.3.9f1) 11.0.0 (2021.1.8f1) 12.0.0 (2021.2.0a18)
Not reproducible with: 4.10.0 (2018.4.35f1), 7.6.0 (2019.4.27f1)
Devices reproducible with:
iPad Air4 (iOS 14.0)
Devices not reproducible with:
iPad Pro 12.9 1st gen (iOS 13.4.1)
Notes:
1. The project uses URP, I am not sure if it is related to the memory problem
2. The issue only occurs when using USB-C connection
3. The customer provided testing results using different devices (clearly visible that issue is present with USB-C port only)

After seeing this issue with our project I have managed to make a build in 2021.1.13f1 which successfully connects to an external monitor without the Metal allocation causing the app to crash.
The changes I made to the projects settings were:
- Set Active Input Handling to: Input System Package (new) and ensure all Event System objects are using the new module
- Check 'Metal Write-Only Backbuffer'
- Set Memoryless Depth to 'Automatic'I also ensured that no cameras were assigned to Display 2 in the editor and assigned them with code after a short pause.
The build has been running on 5 iPads for 8 hours at a time with no issues so I'm confident this does resolve the problem.

Yes please, help Unity!
Our Tagtools desperately needs to be hooked on an external display.
